3*(6/5 - x) 7*x 1 4*(13*x - 3/5) ----------- - 5 + --- = x + 9*x + ---- - -------------- 10 4 5*20 5
3*((6/5)-x)/10-5+7*x/4 = x+9*x+(1/5)/20-4*(13*x-(3/5))/5
3*6/5-x)/10-5+7*x/4 = x+9*x+(1/5)/20-4*(13*x-(3/5))/5
3*6/5-x)/10-5+7*x/4 = x+9*x+1/5/20-4*13*x-4*3/5)/5
-116/25 + 29*x/20 = x+9*x+1/5/20-4*13*x-4*3/5)/5
-116/25 + 29*x/20 = 49/100 - 2*x/5
x = 513/100 / (37/20)
